Abstract: A bin comprising a vessel and a pivoting lid that can be moved between an open position and a closed position. The lid and the vessel are arranged in such a manner that the air leaving the vessel during closure of the lid and when the lid is close to its closed position is forced to turn at least twice, being forced to pass between substantially vertical surfaces belonging respectively to the lid and to the vessel, at least at the front of the lid, preferably at least at the front of the lid and on both sides therefore, and more preferably still all round the four edges of the lid, so as to encourage the creation of raised pressure inside the vessel, which raised pressure tends to brake the displacement of the lid towards its closed position.

Abstract: A locking mechanism (7) for the cover (2) of a container (1), especially a garbage can or dumpster, that is emptied by tilting. The mechanism (7) includes a pivoting part (10) pivotably mounted on the cover (2) of the container (1). When the container (1) is tilted, the pivoting part (10) moves from a locked position to an unlocked position by force of gravity. The pivoting part (10) includes a lower arm (13) capable of engaging a catch member such as a lug (16) when the cover (2) is closed and when the pivoting part is in a position to lock the cover. The invention further relates to a container (1) equipped with such a locking mechanism (7).

Abstract: A playground toy for a seated user, which toy includes a coil spring, the lower end of which spring is fixed to a device for anchoring the toy in the ground and the upper end of which spring is fixed to a three-dimensional structure for supporting the user. The user support includes a rigid reinforcement secured to a connection piece and also includes a stress-distribution piece, preferably frustoconical, at least partially set into a housing or onto a boss of corresponding shape formed in the three-dimensional structure.
